Hi, I was just wondering if I can pick your collective brains...
I've recently developed a problem with my CH, narrowed down to the pump.
A few months ago I had a problem where the pump wasn't working but when I removed the bleed screw I found the pump to be seized...a quick spin with a screwdriver and it started working fine.
A couple of days ago, again no CH, boiler cutting out sounding very hot. I removed the bleed screw again, released the pump which now spins very easily. The problem is when the boiler fires up and the pump is meant to start pumping, it doesn't (at any speed) until I remove the bleed screw and give it a 'jump start' with a screw driver when it then runs normally. If I lower the speed to 1, it stops again and I have to use the screwdriver to start it up once at speed 3. The system has been bled ok and the FE tank is as it should be. I'm guessing the pump is well over 10yrs perhaps double that...is this terminal and should I just replace the pump?
Cheers in anticipation,
Simon
